The best way to keep this as an actual challenge would be to use a Play Now! Human, because starting at a civ makes you extremely powerful, as well as well equipped, while every single Play Now! Human I've ever played as has had abysmal skills. Also, as of 0.31.10, (maybe .09, but I first noticed it in .10) you start with a copper spear and a copper large dagger when you select a Play Now! Human.
